Webb24 mars 2024 · To find the slowness vectors that maximize the amplitude of our 215-s phase, we performed array stacking assuming a range of slowness vectors for each source bin and found the 215-s-phase amplitude on the stacked cross-correlation functions for each slowness vector, which is defined as the maximum amplitude in the time window … Webb1 jan. 2009 · We have developed a novel technique to determine the slowness vector of S waves detected in a linear array of receivers in an isotropic medium. We combine the S …

Webb22 nov. 2024 · The basic role in the expressions for the reflection and transmission coefficients is played by complex-valued slowness vectors of incident and transmitted waves. Real-valued parts of slowness vectors are called propagation vectors and imaginary parts are called attenuation vectors. WebbThus, the slowness vector (to be found) can be presented as a linear combination of two unit-length vectors: the polar axis and the ray velocity directions, with two unknown scalar coefficients. The axial energy propagation is considered as a limit case. grass boy

Webb17 juli 2024 · The slowness vector describes the full perturbation of the wavefield essentially combining the information from backazimuth and horizontal slowness. The radial pattern and magnitude of the vectors around the circular feature southeast of Africa (35°S, 30°W) support our interpretation that this structure is the cause of our observations. Webb26 nov. 2024 · The associated slowness vector of a particular reflected wave is resolved to yield its properties, i.e., phase velocity, attenuation angle, propagation direction and attenuation coefficient. A 4 × 4 energy matrix represents the energy fluxes of reflected waves and interaction energy. Webb1 juni 1997 · The slowness vector, which is typically transformed into bearing and velocity, is a key parameter used for identifying seismic phases and for event source location. … grassboy exotics beaver dam wi
